This Dex adapter worked great with my Samsung Galaxy Note 9 and Otter Defender series case. Incidentally, in the other case, the hole was too small for the USB-C port. Luckily, I did without this cover, which allowed me to give this article full marks. The Dex function worked automatically and instantly. Unfortunately, as far as I can tell, there's no way to output 4K resolution. It seems you can only output the phone's native resolution, which fortunately is greater than 1080p. Dual USB 3.0 connectivity, on-the-go charging, and an optional USB Type-C port make this Dex adapter ideal and affordable. I've found that using a Bluetooth mouse can easily free you from an extra flash drive port or SD card adapter. I now enjoy using the HP Touch-to-Pair Mouse, H4R81AA. This is such a powerful phone that it can truly give you a desktop-like experience.
